Sometimes it's just way too hard,

sometimes it's not. But, believe me, when things get rough, brother, YOU GOTTA FACE IT!
There's no way out. You might shake and fall down or you can stand up and go for it. Try to change the reality of the game. Not for the others, but for yourself.
In the end, in all the fights that life puts you through, it's you against yourself. Against your own devils and difficulties. It is not worthed to spend all your energy trying to make the others change, by giving them lessons of any kind. Absolutely no gain.Personally speaking, of course. Right, I confess, your ego might rise for some instants. But it would all be so small compared to your real wish and to your expectations that undoubtedly you would end up frustrated.
And now comes the part that shows clearly that the fight is against yourself. If something pisses you off, it's you the one who has to make something happen and change the situation, in order to avoid this frustration. Complaining might be useful for relaxing, but plans have to be put in action. Wash your face deeply, breathe... ROUND 2: FIGHT!
